Expert Solution

Step 1

First thing is to the Formula of the compound is

N2O5

first use Stiochemitry

1mole of N2O5 will have --->2 x 6.022 x 10^23 atoms

So, 5.74 x 10^21 will have ---> Z moles.

Z Moles = 4.76 x 10^(-3) mol

Compound have Z moles now

1mol of Compound N2O5 have 16 x 5 grams of oxygen.

So Z moles [4.75 x 10^(-3)]of this compound will have
